I just had a very nice but brief chat with Supreem on the Arena Test Center. I asked him if he can set up another test shard to allow copying of chars from Siege/Mugen. He said he would think about it. So keep your fingers crossed and if you have characters on other shards you can copy to the Arena Test Center, maybe ask him yourself *nicely* if he'll consider it. He told me that the current Arena Test Center just won't accommodate copying from Siege/Mugen because the ruleset makes the character data incompatible.
